Assessment of germinability, productivity and cost benefit analysis of Picrorhiza kurrooa cultivated at lower altitudes

Cultivation of Picrorhiza kurrooa Royle ex Benth, a small creeping, highly medicinal and endangered species of alpine region was observed at comparatively lower altitude than its natural habitat. Germination was observed better inside polyhouse at 15–20°C temperature in sandy soil with litter treatment and high-moisture content. Vegetative propagation was done successfully through stolon segments by using hormonal as well as convenient and simple methods, viz. water-dip treatment and use of high-moisture trenches for rooting in cuttings, which can be easily used for cultivation purpose by local growers. Top segments were found more suitable for multiplication. Yield measured in different landforms, i.e. raised and levelled grounds indicated that the latter was more suitable for better survival, growth and production. Similarly, intercropping with other economically beneficial plants was successfully observed and Foeniculum vulgare and Solanum tuberosum were recommended for intercropping. Forest litter was observed better for higher production by using broad-leaf variety and maximum production was estimated at Pothivasa (1092 kg/ha). For cultivation of P. kurrooa, broad-leaf variety, forest litter treatment, levelled ground and intercropping with plants able to retain moisture in the soil for growing plants, and altitude of 2200 m were endorsed as best for higher production. Cost benefit analysis after third year of cultivation indicated benefits of Rs 87,600/ha based on maximum production. Thus the cultivation of P. kurrooa can provide not only an alternate income-generating resource, but can also provide the opportunity for selfemployment.
